Hi,

only Mesa rebuild is needed at this point.

Yes, it is trying to use the gallium driver still.

The above line should not say Gallium.

Just drop the i915 from the gallium driver list on the Mesa
configure line, and keep it in the dri driver list. Also the configure
line from http://wayland.freedesktop.org/building.html should
work just fine. Intel dri drivers get built by default, when
they are not explicitly configured.

Make sure to wipe all intel drivers from your install prefix before
you install Mesa again, so that the intel gallium driver does not
remain there.

Actually, simply removing the intel gallium driver should be
enough, no need to even rebuild, I guess.
